67213-27-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 67213-27-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,2,1 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 67213-27:
(7*6)+(6*7)+(5*2)+(4*1)+(3*3)+(2*2)+(1*7)=118
118 % 10 = 8
So 67213-27-8 is a valid CAS Registry Number.

Facile synthesis of selenocarboxamides from nitriles using Se/CO/H 2O under atmospheric pressure

Chen, Yahong,Tian, Fengshou,Song, Maoping,Lu, Shiwei

, p. 211 - 214 (2008/09/18)

Aromatic and aliphatic nitriles can be conveniently converted into the corresponding selenocarboxamides with Se/CO/H2O under atmospheric pressure without use of a base.

A facile preparation of aliphatic and aromatic primary selenoamides using 4-methylselenobenzoate as a new selenating reagent

Ishihara, Hideharu,Yosimura, Katsuhiro,Kouketsu, Mamoru

, p. 1287 - 1288 (2007/10/03)

Aliphatic and aromatic primary selenoamides 2 were isolated by the reaction of the corresponding aliphatic and aromatic nitriles with potassium 4-methylselenobenzoate in the presence of BF3·Et2O in moderate from high yields.

Synthesis of primary selenocarboxamides and conversion of alkyl selenocarboxamides into selenazoles

Lai,Reid

, p. 870 - 872 (2007/10/02)

Nitriles react with sodium hydrogen selenide, pyridine and hydrochloric acid in ethanol to give primary aryl and alkyl selenocarboxamides. The alkyl selenocarboxamides are converted into selenazoles by reaction with phenacyl bromide.
